The reason for the IMS was to get rid of the use of timing belts and chains and the need to replace them every $50,000 miles at substantial cost. Definitely not a perfect fix, but then again, no engine is perfect. Toyota and Honda, widely considered to be the paragons of quality, have engine failure issues too.
At the end of the day, I think there is always a trade-off between performance and reliability. The most reliable engine you can get is probably a pushroad inline four. Rock-solid reliable, but heavy and low power. The highest would be a Formula One engine, which needs to be rebuilt after every race.
